Sir Trevor McDonald has reportedly claimed that he would like to do a Neil Diamond impression on The X Factor.

The newsreader's wife apparently told judge Louis Walsh that he is keen to appear on the celebrity version of the show.

According to The Sun, she told Walsh: "You must have Trevor on Celebrity X Factor, he’s such a big fan."

After Walsh claimed that there wasn't going to be another series, she said: "Oh, that’s a shame -Trevor does a great Neil Diamond."
